BURNER FOR NATURAL GAS.

SPECIFICATION forming part of Letters Patent No. 367,945, dated August9, 1887.

Application filed November 1, 1886. Serial No 217,706. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES M. YOUNG, of Corry, county of Erie, andState of Pennsylvania, have invented a new and useful Improve ment inBurners for Natural Gas, of which the following is a full, clear, andexact description, reference being bad to the accompanying drawings,making part of this specification.

My invention relates to a novel construction 0 of natural'gas burner,whereby it is adapted to assist in the operation of effecting a thoroughmixing of the gas with the atmospheric air admitted to the burner, andto the arrangement of the outlet or discharge openings at the peripheryof the burner, whereby the jets are made to converge in pairs, andthereby to draw in an additional supply of oxygen from the air foreffecting a more perfect combustion of the gas.

20. It consists in the combination of two coneavo-convex disks or platesjoined at their edges on their recessed or concaved faces to form achamber between them, one of said plates forming the base-plate andhaving a central inlet-openingthrough which the gas is admitted to thechamber, and the other forming the cap-plate, being provided with apendent convex deflector overlying the inlet-opening and concavity ofthe base-plate, and being arched between said convex deflector and itsouter edge or rim, wherebya rolling motion is imparted to thevolume ofgas and air admitted for effecting a more thorough mixing of the same,and having discharge-openings 5 from said mixing-chambers at the edgesor rims of the plates or disks formed in pairs, those of each pairconverging outwardly in lines oblique to radial lines, all ashereinafter described and claimed. In the accompanying drawings, Figure1 is a side view of my improved burner, showing the connections partlyin section. Fig. 2 is a sectional view of the burner; Fig. 3, an innerface view of the cap-plate, and Fig. 4 a similar View of the base-plate,of the burner.

A indicates the concavoeonvex base-plate, made, preferably, circular inform, though other forms may be used, if desired, and provided with acentral opening, a, screw-threaded for adapting it to be screwed uponthe corre- 5o 4 spondingly screw threaded end of a supplypipe, asindicated. 4

B is the cap-plate, which is also made concavo-convex and of a shapecorresponding to that of the base-plate A, to which it is secured 5 5with its concave side facing the concave side of the baseplate by meansof through bolts or screws a a, or in any other suitable manner. Thecap-plate or dome B is provided with a central pendent portion, b,directly overlying the inlet-opening and concavity in the base, butsufficiently removed therefrom not to interfere with the free admissionof the gas, and made convex on its face overlying said opening, so as todeflect the jet coming through said opening as nearly evenly as may beupon all sides thereof. The concavity of the baseplate adjacent to theinlet-opening facilitates the spreading and mixing of the gases in theevenly as practicable toward the periphery of the burner on all sides,and, secondly, as they are deflected outward and upward until theystrike the roof of the arch, and are there turned downward and outwardtoward the periphery, 8O

to produce a rolling motion of the volume of air and gas, and so toeffect a thorough mixing of the same before they reach thedischargeopenings at the edge or periphery of the burner. The outeredges of the plates A and 8 5 B converge or have rims on their adjacentfaces, and one or both of these, preferably the cap-plate B, has aseries of outlet openings or passages through which the gas escapes atthe periphery of the burner,-where it is ignited. 0 These openings,instead of being radial to the inlet-openin g, are arranged in pairs, aa,whicl1 converge outwardly in lines oblique to radial lines and tend tocause the jets therefrom to converge until they meet and combine their 5flames, or nearly so. By this arrangement of the openings the pairs ofescaping-jets are made to induce a current of air between them,

affording an increased supply of oxygen to and thereby effecting a moreperfect combustion of the gas.

Air is supplied to the interior of the burner in any suitable manner. Ihave shown the pipe 0, with which the burner is connected, provided at asuitable distance therefrom, preferably outside of the stove or heaterto which the burner is to be applied, and which may be of any usual orpreferred kind, with a drum, D, preferably of the hollow spherical formindicated, but which may be in cylindrical or other suitable form, andthrough which the gas received from a pipe, 0, is forced in its passageto the burner. The pipe 0 is preferably of less diameter than pipe 0,and the escape of the gas therefrom is controlled by a valve, 3, of anysuitable form or construction.

The drum D is provided on its side connected with the pipe 0 and aroundthe latter with a series of perforations, d, through which air isadmitted to the drum, drawn in by the movement of the current of the gasthrough the drum into the pipe C and into the mixingchamberof theburner, and is there thoroughly mixed with the gas through the action ofthe deflecting and arching surfaces of the burner thereon, as aboveexplained.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A natural-gas burner composed of the concavo-convex base A, having acentral inletopening, a, for the admission of gas, and theconcavo'convex cap B, having the convex deflector I), located centrallyabove the gas-inlet opening and concavity of the base-plate, the archedor grooved portion 1), substantially as described, and havingjet-openings formed between the abutting edges or flanges of the baseand cap pieces and arranged to converge in pairs in lines oblique toradial lines, for the purpose and substantially as described.

In testimony whereof I have hereunto set my hand this 29th day ofOctober, A. D. 1886.

CHARLES M. YOUNG.
